Introducing the Emotions-Affect Systems Elicitation (EASEL-3) Index: A New Tool for Measuring Affect Regulation Systems' Activation

Abstract

Although emotions pervade and influence individual and interpersonal functioning and well-being, their nature and taxonomy remain a bone of contention. The ‘three-circle’ model, comprising three dynamically interacting affect regulation systems (i.e., threat, drive, and soothing), provides a useful framework for aggregating emotions and understanding emotion (dys)regulation while closely supporting therapeutic intervention. Imbalances in the activation and (inter)action of these affect regulation systems have been implicated in a wide range of physical and mental disorders; however, there are currently no tools for quantifying each system's activation. The aim of this study was to develop a novel index of the three affect regulation systems: threat, drive and soothing.
